Automation summary

• root_cause: The manageStorage tool returns a temporaryUrl after upload, which is a temporary signed URL that expires in 1 hour. The agent incorrectly used this as the permanent publicUrl in internal evaluation artifact. The tool description and skill docs did not provide guidance on how to obtain permanent public URLs for storage objects.
• changes:

1. mcp/src/tools/storage.ts:

• Updated queryStorage tool description to clarify that temporaryUrl is temporary and expires, and added guidance to use envQuery(action=info) to get CdnDomain for constructing permanent public URLs
• Updated manageStorage tool description with the same guidance
• Added a note field in the upload response to remind agents that temporaryUrl is temporary and how to get permanent public URLs

2. config/source/skills/cloudbase-platform/SKILL.md:

• Added a new section "Cloud Storage Public URL" with clear guidance on how to get permanent public URLs using envQuery(action=info) and EnvInfo.Storages[0].CdnDomain

3. config/source/guideline/cloudbase/SKILL.md:

• Updated the Storage Skills section to include a note about permanent public URLs

4. Synced the changes to the Claude skills mirror and bu
